General Description:
NiteCore Extreme is single CR123 battery based flashlight from EDGE Tactical Light Co. Ltd. NiteCore Extreme belongs to NiteCore Tactical series of flashlights from EDGETac. NiteCore Extreme is specially designed for Law Enforcement personal and for self defense. The NiteCore Extreme has two light operating levels both of which are are configurable through light programming and are memorised. LED used in NiteCore Extreme is high efficiency Cree 7090 XR-E Premium Q5 binned WC tint LED. Reflector of NiteCore Extreme is built from solid aluminum with Light Orange Peel (LOP) reflector finish. The Glass lens in front is anti-reflective impact resistant lens with Dual-Coating (TM). Dual-Coating is the specialty diamond coating on outer surface of the lens over the AR coating. The DI Extreme uses digitally regulated electronic drive circuit along with micro controller based programming unit. Brightness levels are controlled by turning the head. The body of NiteCore Extreme is built of military grade aluminum alloy. Light is coated inside out with military spec type III hard anodized finish that is highly suitable for rough usage. HAIII anodizing makes NiteCore Extreme durable and protects from normal wear and tear. The NiteCore Extreme comes pre installed with removable pocket clip on battery tube. The tactical forward type click switch located at the tail cap end has black color rubber boot. The advantage of tactical switch is it allows momentary operation. Battery contact spring at the tail cap switch end is gold plated ensuring very good connectivity with the battery. The positive contact on head is solid aluminum. There are O-Ring seals at various places for waterproofing, NiteCore Extreme meets IPX-8 Waterproof Standard. The Overall build quality of NiteCore Extreme is superb. DI Extreme meets US MIL - STD - 810 F standard resistance to impact by dropping. NiteCore Extreme comes in nice cardboard box packaging along with accessories.
Light Features:
Light Operation: Tactical click switch with momentary mode. For Switching ON / OFF use tail cap switch. Click once to switch on, click again to switch off. For momentary operation soft press the switch.
High Mode: is achieved by fully tightening the head. In default factory setting, the light output is maximum in this mode. Typically 190 lumens on CR123 battery.
Low Mode: Loosen the head for low mode for low light output. Low mode is in deed low light output. Typically less than 10 lumens.
Pictures:
Packaging & Contents: NiteCore Extreme comes packaged card board box. Inside the main card board box, the light is sandwiched in between two foam beds. Operating manual, accessories are placed at the bottom of the box. Inside the box showing NiteCore Extreme flashlight.
Other contents and accessories include warranty card with bar code, operators manual for NiteCore Extreme, Two additional O-Rings, one tailcap switch boot, two additional tailcap switches and tool to remove pre installed pocket clip.
Size Comparison:From L to R: AW RCR123 Battery and NiteCore Extreme.
Bezel Comparison: On the left is NovaTac 120T, where as on right is NiteCore Extreme. The reflector diameter is about 21mm. The beam pattern is very good hotspot with good side spill.
Bezel:Let's have a closer look at the bezel of NiteCore Extreme. The premium binned Cree XR-E LED is aligned perfectly in center. The reflector in NiteCore Extreme built from solid Aluminium. The reflector has Light Orange Peel (LOP) finish ensures perfect beam. Beam pattern for DI Extreme is mostly throw with good side spill free from rings and any artifacts.
Body: NiteCore Extreme is built from military grade aluminium. Body is sandblasted to give a matt finish and has black color military specification hard coat type III anodizing for protection from wear and tear. The built quality of NiteCore Extreme is excellent. The tailcap and installed pocket clip prevent light roll off. Tailcap has means of attaching lanyard. Overall the construction of NiteCore Extreme is fairly strong.
Components: NiteCore Extreme consists of two main components, head, battery tube with tailcap installed. Head houses LED, reflector and electronics where as the battery tube tail cap combo accommodates single CR123 battery. There is no rattle of batteries, AW RCR123 Battery has enough space is there for free movement. Tailcap has switch with rubber boot.
Head: There is a band of diamond shaped knurling on the head for better grip. This additional grip helps to twist head for changing light levels. E3 is laser engraved over the head indicating the drive circuit and electronics are specifically built for 3V - 4.2V CR123 sized batteries this includes standard CR123 battery as well as RCR123 battery. There are five heat radiating fins helping in better heat dissipation Fins typically resemble those found on heat sinks. The fins not only help in heat dissipation but also enhance the cosmetic look of the NiteCore Extreme light.
Manufacturers Note: The E3 printed on the light bezel means it's Light Engine E3 circuit, the input voltage is 2.2V-4.2V, so please be cautious when you use this bezel on other bodies, you should NOT use 2 CR123 batteries, or the light bezel will be damaged due to excessive voltage input.
Battery Tube & Tailcap: Threads on battery tube of NiteCore Extreme are anodized. Threads are lubricated nicely. There is a translucent O-Ring sitting behind the threads. The advantage of anodized threads is it prevents the thread wear during normal usage. This is due to the fact that anodizing provides hard surface of aluminium oxide which is resistant to wear. Diamond knurling on battery tube of NiteCore Extreme offers excellent grip. Battery tube has two flat machined surfaces making a place available for laser engraving. Light model number, LED power, company name and company logo and website address are laser engraved on the flat surfaces.

Update 1: Added Lots of Pictures and Some additional information here...
Beamshots will post by evening.... waiting to get dark
... Very good beam and tint is my initial impression....
It appears that nitecore site is not yet updated, if you are interested in this light, please visit CPFMP Sales & Informaiton Thread from EDGETAC: 177497
Update 2: OK now we have some of the things setup...and completed...
First let's talk about the total output as many have wondered the difference between the two. NDI Silver and NDI Extreme. The NDI Extreme indeed has more output with same chemistry battery Li-Ion.
The output is different. Here is the chart. <edit> chart removed, see update 4
Beamshots are done, Resizing and posting soon in a few moments....
Update 2: Beamshots 1
More beamshots Here...
Update 3: Beamshots 2 Here is the comparison between beamshots of NiteCore Extreme and NiteCore Defender Infinity Silver
More here...
Update 4: Comparitive Output Here is the comparison chart for outputs of NiteCore Extreme and NiteCore Defender Infinity Silver with various battery types and conditions
From the above chart it is clear that there is a distinct difference between outputs of NiteCore Extreme and NiteCore Defender Infinity Silver. Please be aware that the sample size is ONE and there is always a variance in battery, electronics and LED. Some times LED may be one off the premium. Some tmes batteries may be underperforming. In short, there are a lot of factors that affect the total light output. The fact remains that light output of NiteCore Extreme is higher than NiteCore Defender Infinity Silver for similar battery chemistries. selfbuilt in his initial views has also confirmed the fact. I will update this section as soon as his review is posted.
Update 5: Extreme Close Up Pictures Here are a couple of extreme closeup pictures for NiteCore Extreme
More here...
Update 6: Runtime Test: The runtime for NiteCore Extreme with AW RCR123 on MAX light output is about 47 Minutes till 50% . NiteCore Extreme runs completely in regulation. Runtime for NiteCore Extreme for lesser output levels will be considerably more. From the runtime, it is evident that NiteCore Extreme has one of the efficient circuits out there. It is as of till date the best combinaiton for longest running and highest brightness.
These results are in line and similar to selfbuilt's results prooving consistancy in light runtime for different samples. More excellent runtime tests by self built can be viewed on selfbuilt's excellent review thread
